Around 12 hours 32 minutes to beat. Stage 4-1 alone took just under 12 hours to beat. The rest of the game ranges from very easy to moderate. Its a very random difficulty spike. At some point I reached a skill ceiling where it was more of a gambling game. Once you have the skill to snipe out and break through a single column, its more of a dice roll if the ball goes into ATTACK mode and takes out the rest of the blocks. In the upcoming tutorial version I will break down my strategies.
Failed attempts edited out. You get 3 balls for each credit. This game has unlimited continues and starts you on the last stage you got to.
